E.3 | Principal inclusion criteria |
[1] Patients are at least 2 years and less than 18 years of age.

forms of JIA as defined by ILAR criteria:
Polyarticular JIA (positive or negative for RF)
Extended oligoarticular JIA
ERA
JPsA
[3] Have had an inadequate response or intolerance to treatment with ≥1 conventional or bDMARD.
[4] Patients with polyarticular JIA or extended oligoarticular JIA must have at least 5 active joints at screening and baseline. Those with JPsA must have at least 3 active joints at screening and baseline. Those with ERA must have (a) at least 3 active joints at screening and baseline or (b) involvement of at least 1 sacroiliac joint AND a physician global of at least 3 (on the 21-circle numeric rating scale [NRS]).
[5] Both the child or adolescent and a parent or legal guardian are able to understand and fully participate in the activities of the clinical study and sign their assent and consent, respectively, accordance to local guidelines.
[6] Male or nonpregnant, nonbreastfeeding female patients. Patients of child-bearing potential who are abstinent (if this is complete abstinence, and their preferred and usual lifestyle). Otherwise, patients and their partners of childbearing potential must agree to use 2 effective methods of contraception. |
|
E.4 | Principal exclusion criteria |
[7] Have systemic JIA, as defined by ILAR criteria, with or without active systemic
features.
[8] Have persistent oligoarticular arthritis as defined by ILAR criteria.
[9] Have a history or presence of any autoimmune inflammatory condition other than JIA, such as Crohn’s disease or ulcerative colitis.
[11] Have active fibromyalgia or other chronic pain conditions that, in the investigator’s opinion, would make it difficult to appropriately assess disease activity for the purposes of this study.
[12] Have a current or recent (<4 weeks prior to baseline) clinically serious viral,
bacterial, fungal, or parasitic infection or any other active or recent infection that, in the opinion of the investigator, would pose an unacceptable risk to the patient if participating in the study.

[17] Have a positive test for hepatitis B virus (HBV) at screening.
[18] Have hepatitis C virus (HCV) infection.
[19] Have evidence of human immunodeficiency virus (HIV) infection and/or positive HIV antibodies.
[21] Have evidence of active TB or latent TB.
[22] Major surgery within 8 weeks prior to screening or requiring major surgery during the study.
[23] History or presence of cardiovascular, respiratory, hepatic, gastrointestinal,
endocrine, hematological, neurological, or neuropsychiatric disorders or any other serious and/or unstable illness.
[24] History of a VTE or are considered at high risk of VTE as deemed by the
investigator.
[25] Largely or wholly incapacitated, such as being bedridden.
[26] History of lymphoproliferative disease; or have signs or symptoms suggestive of possible lymphoproliferative disease, including lymphadenopathy or splenomegaly; or have primary or recurrent malignant disease.

The dose of cDMARDs is expected to remain stable throughout the study and may be adjusted only for safety reasons.
[32] MTX use at doses of >20 mg/m2/week.
[33] Are currently receiving concomitant treatment with combination of >2 cDMARDs (including MTX).
[51] Have experienced hypersensitivity to the active substance or to any of the excipients. |
